The Joshua Slocum Society International (JSSI), located in Bethel (CT), is a non-profit corporation first incorporated in 1972. It was founded in 1955 by sailing enthusiast Richard Gordon McClosky to record, encourage, and support long distance passages in small boats. In pursuit of these goals it has become an international association of people of similar interests:
First, in reporting and recording the adventures of small boat sailors.
Second, in recognizing significant voyages and acts of heroism at sea.
And third, in keeping sea history alive, especially the memory and legacy of Captain Joshua Slocum.
In June 1998, the Society promoted and attended ceremonies in Bristol and Newport, R.I. and Fairhaven, Mass. celebrating the centennial of Joshua's return from his solo voyage around the world.
The Society's burgee (flag) is the house flag of the last commercial sailing outfit that employed Joshua Slocum.
The burgee is a square white flag with three rows of three square diamonds each.
